DOE tests Indiana formation for CO2 storage potential
Storage, Nov 16 2009 (Carbon Capture Journal)
- The DOE's Midwest consortium has begun injecting 8,000 tons of CO2 to evaluate the carbon storage potential and test the enhanced oil recovery (EOR) potential of the Clore Formation in Posey County, Indiana.
The injection, which is expected to last 6-8 months, is an integral step in DOE’s Regional Carbon Sequestration Partnership program. The Midwest Geological Sequestration Consortium (MGSC) is conducting the field test to assess the most promising strategies for deploying CCS in the Illinois Basin.
In addition to evaluating the Clore Formation as a storage site, the project is assessing the potential for EOR in wells that were previously producing oil, but are now abandoned.
The three-member project team, composed of the Illinois State Geological Survey at the University of Illinois, the Indiana Geological Survey, and Gallagher Drilling Inc., is injecting CO2 into the Mumford Hills oilfield at a depth of about 1,900 feet. The injection well is located among four oil-production wells about 5 miles northeast of New Harmony, Ind.
The full duration of the project will depend on the capability of the reservoir to serve as a storage site, as well as the number of water and CO2 injection cycles that will be needed to reach project goals.
A monitoring, verification, and accounting effort is underway at the site to monitor air and groundwater quality; measure the amount of produced oil, gas, and water; monitor CO2 injection composition, volumes, and rates; and monitor injection pressure and temperature.
